Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
13. The clock delay detection device according to claim 12, wherein the first calculating sub-module configured to acquire the phase relationship between the feedback clock and the self-loop back clock comprises, the first calculating sub-module selects clock data from the feedback clock and performs a phase detection on the clock data with the self-loop back clock to determine the phase relationship.
This invention relates to clock delay detection in digital systems, specifically addressing the challenge of accurately measuring phase differences between clock signals to ensure synchronization in high-speed data transmission or processing. The device includes a first calculating sub-module designed to determine the phase relationship between a feedback clock and a self-loop back clock. The sub-module selects specific clock data samples from the feedback clock and performs a phase detection operation by comparing these samples with the self-loop back clock. This comparison identifies the phase offset between the two clocks, enabling precise timing adjustments to maintain system synchronization. The invention improves upon existing methods by enhancing the accuracy and reliability of phase detection, which is critical for applications such as clock recovery, signal synchronization, and timing error correction in digital circuits. The device may be integrated into larger clock management systems or used as a standalone module for real-time phase monitoring and adjustment.
14. The clock delay detection device according to claim 12, wherein the first calculating sub-module is configured to acquire at least two phase relationships between the feedback clock and the self-loop back clock, and the second calculating sub-module is configured to determine a corresponding delay value based on each of the at least two phase relationships.
A clock delay detection device is designed to measure and compensate for timing discrepancies in clock signals within digital systems, particularly in scenarios where precise synchronization is critical. The device addresses the challenge of accurately detecting and quantifying delays between a feedback clock and a self-loop back clock, which are essential for maintaining system stability and performance in high-speed data processing and communication applications. The device includes a first calculating sub-module that acquires at least two phase relationships between the feedback clock and the self-loop back clock. These phase relationships represent the temporal differences between the two clock signals at different points in time. A second calculating sub-module then processes these phase relationships to determine a corresponding delay value for each relationship. By analyzing multiple phase relationships, the device can provide a more accurate and reliable measurement of the delay, accounting for variations and noise that might affect a single measurement. This multi-phase approach enhances the precision of delay detection, ensuring that timing adjustments are made with high fidelity, which is crucial for applications such as phase-locked loops (PLLs), clock data recovery (CDR) circuits, and other timing-sensitive systems. The device's ability to handle multiple phase measurements improves its robustness in dynamic environments where clock signals may fluctuate.

A clock delay detection device is used to measure and analyze timing delays in digital or analog clock signals, which is critical for ensuring synchronization in electronic systems. The device includes a fourth calculating sub-module that processes at least two delay values according to a predetermined rule to generate a processed delay value. This processed value is then used, in combination with delay parameters, to determine the final delay measurement. The delay parameters may include factors such as environmental conditions, signal characteristics, or system-specific calibration data. The device ensures accurate timing adjustments by refining raw delay measurements through mathematical operations, improving the reliability of clock synchronization in applications like telecommunications, computing, and signal processing. The system may also include other sub-modules for capturing, filtering, or analyzing clock signals to enhance measurement precision. The overall goal is to mitigate timing errors that could disrupt system performance, particularly in high-speed or high-precision applications.

A clock delay compensation device is designed to address timing inaccuracies in digital systems caused by signal propagation delays. The device includes a clock delay detection module that measures the delay between a reference clock signal and a clock signal to be compensated. The detection module generates a delay value representing the measured time difference. The compensation device also includes a compensating module that receives the detected delay value and adjusts the clock signal to correct for the measured delay. The compensating module may use techniques such as phase shifting, frequency adjustment, or digital delay lines to align the clock signal with the reference clock. This ensures synchronization between different components in a system, improving performance and reliability in applications like high-speed data processing, telecommunications, and embedded systems. The device is particularly useful in environments where precise timing is critical, such as in microprocessors, FPGAs, and clock distribution networks. By dynamically compensating for delays, the system maintains accurate timing relationships, reducing errors and enhancing overall system efficiency.
